Xena, Is this what I think it is? Much is beyond me but the repeats are playing back in one comprehensive piece what we have seen bits of here for years.
Alzheimer's after age 70 who takes a high dose of AVXL 2-73 would be able to live out their life until death with a much lower reduction in ability to think and remember. This would result in patients still remembering their life while being able to live on their own if they are otherwise healthy enough to do so.
